SUPPORT FOR BIVETING-TOOLS.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application'filed May'IO, 1920. Serial No. 380,320.

To all whom it may concern:

Be it known that I, ALoNzo WoLrANcER, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in Supports for Riveting- Tools of which the following is a specification.

This invention relates to supports for riveting tools and it has more particular reference to what may be termed adjustable pedestals or stands, the main object being to provide a stand for a riveting hammer by the use of which said hammer can be employed for riveting in awkward positions and where it has been necessary heretofore to employ at least two men, one to support the hammer and another to manipulate and operate the same. 7

Another object of my invention is to provide a support for riveting hammers by which the Weight of the tool is counterbalanced in such a manner that it can be readily handled by one operator whereby a great saving in labor and time is effected.

Still further the invention has for an object to provide a support whereby the riveting hammer can be held in any desired position and manipulated under a flat, inclined or curved surface with perfect ease. 7

With the foregoing and other objects in view as will later on be more apparent this invention consists essentially in certain novel features of construction, combinations and described and more specifically'defined by the appended claims,

In the further disclosure of the invention reference is to be had to the accompanying sheet of drawings constituting a part of this specification in which similar characters of reference designate the same or corresponding parts in all the views.

Figure 1 is an elevation of my improved support for riveting tools, parts being A broken away for the sake of clearness.

Fig. 2 is an enlarged fragmentary detail of'a portion of the pedestal and counterbalance, with parts in section to better disclose the underlying structure; and

Fig. 3 is a detail plan of a supporting member hereinafter more specifically referred to.

Referring to the drawings, the numeral 10 designates flattened arch members provided with laterally projecting feet 11 and disposed in cruciform manner to intersect at their flattened parts 12. These arched members 10 at their point of intersection are perforated and screw threaded at 13 to receive the correspondingly threaded end of a vertical tubular section or standard 14, in which is slidably fitted a rod or bar 15, the lower end whereof is reduced at 16 to seat m a trunnion ring or bearing 17 pivotally mounted in the forked end 18 of a lever 19. This lever 19 is provided with a pivot pin 20 or opposed laterally projecting pintles adapted for seating in opposed inclined slots or notched out parts 21 formed for their reception in a pair of spaced'depending links 22 appropriately suspended by a pivot pin or bolt 23, transversely projecting from the vertically twisted or turned part 24 of a horizontally disposed supporting element or flat iron 25 preferably clamped between the lower flanged end 26 of the aforesaid tubular standard 14 and the intersecting flattened portions 12 of the arched members 10, forked pro ections or extensions 27-Fig. 3thereof being secured by bolts or rivets 28 to the flattened out parts of the said arched members whereby a rigid structure is secured when the several parts are assembled as shown.

Adjustable longitudinally of the lever 19 by means of cotter pins ,or bolts 29 is a sad dle box or receptacle 30 in which may be deposited weights 31 of different-weight, for

the purpose hereafter explained. arrangements of parts as hereinafter fully Integral with or firmlysecured on the upper end of the slidable rod or bar 15 is an inverted stirrup bearing 32 transversely of which is rotatably mounted a grooved roller 33 that constitutes a support for a tubular or round iron bar 34 on one end whereof is swivelingly mounted an upstanding antifriction roller or caster 3 the other end of said bar being provided with an eyed portion 36 from which de ends a stirmp 37, having opposed slots 38 for the reception of pintles 39 on a locking ring 40 adapted for clamping engagement on the barrel -ofthe riveting hammer 41, it being readily understood that the said hammer also projects upwardly through the eyed portion 36 of the bar and that its head or handle portion seats on the lower part 42 of the stirrup 37. It is also to be particu larly noted that when the hammer 41 is mounted in the stirrup 37 as shown, that the barrel and die 43 project thereabove only sufficient to insure the bar 34 remaining in a substantially horizontal plane when the device is in use under a flat surface as indicated by the dot-and-dash line 44; or, as will be readily understood by those skilled in the art of riveting, the die 43 of the hammer 41 is always in direct alinement with supporting said hammer and is free to manipulate the same promptly and expeditiously over the desired seam or surface; while the prompt. dismantling of the entire device can be readily effected and thereby rendering'said device easily portable and compact for shipment.

From the foregoing description of the embodiment of my invention shown by the accompanying drawings it becomes clear that I have provided an eflicient means for supporting a riveting hammer and I wish it clearly understood that I do not limit myself to the precise details of shape or the particular arrangement and combination of parts disclosed, as various, slight changes can be readily evolved without departing from the spirit and scope thereof as more particularly defined by the appended claims.
